11 digital input/output pins, all pins have interrupt/pwm/I2C/one-wire
 
supported(except D0)
 
1 analog input(3.3V max input)
 
a Micro USB connection
 
 
 
 
 
How to get started in :
 
    Setup driver
 
Before you use miniD1 boards, you need setup CH340g driver.
 
    Python
 
On Windows you need install Python 2.7.10.
 
On Linux & MAC OSX, you don't need install it, comes preinstalled with OS.
 
    Installing Hardware package
 
There is two ways to install hardware package, Boards Manager or GIT
 
    Installing with Boards Manager
 
Starting with 1.6.4,for Arduino allows installation of third-party platform packages using
 
Boards Manager. We have packages available for Windows, Mac OS, and Linux (32 and
 
64 bit).
 
<1>. Install for Arduino 1.6.7 from the for Arduino website.
 
<2>. Start for Arduino and open Preferences window.
 
<3>
into Additional Boards Manager URLs field. You can add multiple URLs, separating them
 
with commas.
 
<4>. Open Tools→Board:xxx→Boards Manager and install esp8266 by ESP8266
 
Community (and don't forget to select your ESP8266 board from Tools > Board menu
 
after installation).
 
    Installing with GIT (Recommend):
 
We recommend using GIT to install Hardware package,
 
you can always get the latest version of it.

Kit parameters:
Power supply voltage: 4.5-5.5V (DC voltage, 3 battery boxes are recommended)
Board size: 2.5*3.5cm
Buzzer: 5V passive buzzer, the sound of tap-tap-tap is small, please carefully if you mind!!
Function Introduction:
After power on, NE555 outputs a certain frequency of square wave pulse. The high level lights one lamp and the low level lights the other lamp, so the two LEDS flash alternately and there is a clicking sound.
This kit needs to be welded and installed by the buyer himself.
 
 
Circuit introduction:
The core component of this circuit is the 555 integrated timer, which works in the non-steady mode. After the power is switched on, the 3pin level at the output end of the 555 integrated timer constantly changes its high and low level. When the 3pin is at high level, LED1 goes out and LED2 shines.
When the 3 feet are low, LED1 shines and LED2 goes out. At the same time, capacitor C3 discharges through the loudspeaker, and the loudspeaker makes a "tap" sound.
So the leds light up alternately, and the speakers make a tap-tap-tapping sound.
